- fixes image uploads on settings/general by reverting to jQuery for triggering the file dialog because IE11 doesn't support `MouseEvent` events or have the `.closest` method on native DOM elements
- gives all SVG elements an explicit `width` and `height` - if one property is set to `auto` or not specified IE11 will treat it as 100% of the container
- fixes horizontal scroll + scrollbar on the main app viewport
